torx bit for tps removal

I am going to pick up an 89 cherokee tonight. It sounds like the tps isnt adjusted right so I am going to take my meter along and check it out before I try to drive it. I am away at school without my tools. Anybody know what size the torx are that hold on the tps so I can adjust it, I dont want to buy a whole set since I already have nice one back at home. Thanks

The TPC and IAC are both #20 torx.

I blieve on the IAC you'll need a 'tamper proof' T-20...but you can use it to remove both TPS and IAC.
